This is a Flask-based web application that uses PostgreSQL as its database. The project is containerized using Docker and Docker Compose for easy deployment and management. The endpoints available will be:

1. GET / - Home Route
2. GET /users - List all users
3. POST /users - Create a new user
4. PUT /users/<id> - Update a user
5. DELETE /users/<id>/ - Delete a user

1. Clone the repository and navigate to project directory.

   git clone https://github.com/keploy/samples-python.git
   cd samples-python/flask_postgresql_app

2. Install Keploy.

    curl --silent -O -L https://keploy.io/install.sh && source install.sh

3. Build and run the Docker containers:

   docker compose up --build

4. Access the application: Once the containers are running, the Flask app will be available at:

   http://localhost:5000

5. Capture the testcases.

   keploy record -c "docker compose up" --container-name "flask_web_app" 

6. Generate testcases by making API calls.

   Home Route

   GET /

   curl -X GET http://localhost:5000

   # Retrieves a list of all users.
   # GET /users
   curl -X GET http://localhost:5000/users \

   # Create a new user by providing a name.
   # POST /users
   curl -X POST http://localhost:5000/users -H "Content-Type: application/json" -d '{"name": "Harsh"}'
   

   # Retrieve a user by their ID.
   # GET /users/<id>
   curl -X GET http://localhost:8000/users/<id>/ \
   

   # Update the name of a user by their ID.
   # PUT /users/<id>

curl -X PUT http://localhost:5000/users/ -H "Content-Type: application/json" -d '{"name": "Updated Name"}'

  ```bash
# Delete a user by their ID
# DELETE /
curl -X DELETE http://localhost:5000/users/<id>

Replace `<id>` with the actual ID of the item you want to retrieve, update, or delete.

## Run the testcases
```bash
keploy test -c "docker compose up" --container-name "flask_web_app"
